Adding new Calendars does not succeed

[3DJupp]

At the moment you can edit and remove Calendars via Configpage, but, adding won't succeed.
There is a problem with the formatting in Javascript.
This is what it looks like, when you want to add another calendar.
You'll get twice the amount of colums, when adding it. Even the alignment is not correct, when navigating via "TAB" Key to the next textbox

Hi Dominik,
I downloaded and installed the latest version . So I have not this issue. I use Windows 10 , Chrome browser . Here I can enter calendar , change, and delete without any issues .

Is that in my case , or have you already corrected this issue?
